B-vitamins are essential for energy metabolism, nervous system function, and red blood cell formation. Most budget B-complexes use cheap, synthetic forms that many people cannot convert effectively.
Our formula uses methylated B12 (methylcobalamin), active folate (methyltetrahydrofolate), active B6 (pyridoxal-5-phosphate), and riboflavin-5-phosphate — the forms your body can use directly.
